【】ue上報(bào)measurementControlFailure 的原因

 


在一個(gè)ue log中看到
message measurementControlFailure :
  {
   rrc-TransactionIdentifier 2,
   failureCause configurationIncomplete : NULL,
   laterNonCriticalExtensions
   {
    v590NonCriticalExtensions
    {
     measurementControlFailure-v590ext
     {
      rrc-TransactionIdentifier-MSP-v590ext 0
     }
    }
   }
后經(jīng)過(guò)咨詢(xún)r(jià)nc人員,確定是rnc參數(shù)配置問(wèn)題:把異頻鄰區(qū)配置了readsfn=true
之前的測(cè)量控制消息如下:

   }
}


原因在25.331協(xié)議中有相關(guān)規(guī)定(8.4.1.3節(jié)):

1>  if the IE "Read SFN indicator" included in the IE "Cell info" of an inter-frequency cell is set to TRUE and the variable UE_CAPABILITY_TRANSFERRED has the DL "Measurement capability" for "FDD measurements" set to TRUE (the UE requires DL compressed mode in order to perform measurements on FDD):
2>  set the variable CONFIGURATION_INCOMPLETE to TRUE.
而ue的后續(xù)動(dòng)作如下:
8.4.1.4a  Configuration Incomplete
If the variable CONFIGURATION_INCOMPLETE is set to TRUE, the UE shall:
1>  retain the measurement configuration that was valid before the MEASUREMENT CONTROL message was received;
1>  set the IE "RRC transaction identifier" in the MEASUREMENT CONTROL FAILURE message to the value of "RRC transaction identifier" in the entry for the MEASUREMENT CONTROL message in the table "Accepted transactions" in the variable TRANSACTIONS and clear that entry;
1>  clear the variable CONFIGURATION_INCOMPLETE;
1>  set the cause value in IE "failure cause" to "Configuration incomplete";
1>  submit the MEASUREMENT CONTROL FAILURE message to lower layers for transmission on the DCCH using AM RLC;
1>  continue with any ongoing processes and procedures as if the invalid MEASUREMENT CONTROL message has not been received;
1>  and the procedure ends.
